4 Claims.

1 This invention relates to firearms and more particularly to an improvement thereof constituted by a new and useful means by the provision of which the firearm barrel, receiver, and a tubular cartridge magazine Will be positively located in respect to each other and to the firearm butt stock, when the firearm is assembled.

One object of this invention is to provide in a firearm cooperating means to locate a tubular magazine in respect to a receiver.

Another object is to provide in a firearm cooperating means to locate a cartridge guiding throat in respect to the magazine and receiver of said firearm.

A further object is to provide in a firearm means to locate and assemble the receiver and tubular magazine properly located in respect to each other to a barrel extending from the receiver.

A further object is to provide improvements in firearms which will be relatively inexpensive to manufacture, simple in construction, compact, of pleasing appearance, and very efficient and durable in use.

With these and other objects in view, which will appear as the description proceeds, there has been illustrated in the drawings two forms in which the features and principles of this invention may be conveniently and practically embodied.

In the drawings:

Figure 1 shows broken and partially sectioned portions of a firearm embodying the features and principles of this invention;

Figure 2 is an end view of the same;

Figure 3 is a cross-sectional view taken on the line 33 of Figure 1;

Figure 4 is a vertical sectional View taken on the line 4-4 of Figure 3; and

Figure 5 is a view showing a slightly modified form.

Referring now to the drawings wherein like reference numerals designate like parts throu hout the several views, the reference numeral H denotes a firearm receiver of hollow cylindrical form. The breech end l2 of a barrel is is inserted in the forward end of the receiver, wherein it snugly fits, and is secured therein by a cross pin [4. A tubular cartridge magazine !5 extends along the barrel 83, being spaced Slightly below the same. A cartridge guidin throat it, having an end ll received in the rear end it of the magazine I5, extends upwardly at an angle to the axis of the magazine into the receiver I l.

Th receiver 5 i is provided in its underside, with a forwardly and downwardly inclined groove It in which the throat I6 is adapted to seat, and with an arcuate groove 2! leading inwardly from its front end and being generally parallel to the axis of the receiver in which the rear end is of the magazine is adapted to seat. The lengthwise axes of grooves I 5 and 2! are substantially in alignment whereby the throat l6 and magazine i5 will be properly located in respect to each other and to the receiver when they are seated in the grooves is and 2! respectively.

The breech end 22 of the barrel it is of smaller diameter than the portion of the barrel extending out of the receiver H, whereby a rearwardly directed annular shoulder 22 is formed on said barrel. An assembly lug 23 is provided and has an opening 24 therein to rotatively receive the breech and Q2 of the barrel 13. Below the opening 24, the assembly lug is provided with another opening 25 through which the tubular magazine i5 extends and is rotatable therein. The openings 2d and 25 in the assembly lug 23 are spaced apart the proper amount to insure the desired location of the magazine 15 in respect to the barrel iii.

The assembly lug 23 is generally L-shaped in cross-section having an upper plate portion 26 proportionally long in length in respect to a shorter tongue portion 2?, which tongue portion 21 is substantially at right angles tothe plate portion 26. The openings 24 and 25 are formed in the plate portion 25. The tongue portion 2? has a threaded hole 28 therethrough to receive an assembly screw 29 by which a firearm butt-stock 3! is fastened to the assembly lug 23.

The above firearm parts are assembled by first slipping the barrel breech end !2 through the opening 2 3 in the lug plate portion 26 until the latter abuts the shoulder 22. The receiver H is then pressed onto the breech end l2 and tightly up against the lug plate portion 25, and the pin i l, the holes for which have been previously formed and properly located in both the receiver If and in the barre1 breech end [2, is inserted. The magazine It is now slipped through the opening 25 in the lug plate portion 26 and the assembly lug 23 is rotated on the barrel breech end i2 until the magazine end ill aligns with the groove 2! in the receiver 5 i, whereupon the magazine i5 is firmly ressed rearwardly into abutment with a shoulder 32 at the rear end of the groove 2!. The cartridge guiding throat end I! is now pressed into the end it? of the magazine and seated in the groove is in the receiver H. The butt-stock 3i is now disposed upon the assembled parts with the tongue portion 2'! seated in and located by a cut out depression 33 in the butt-stock 3i and clamped to the assembly lug 23 by screwing the screw 29 into the threaded hole 28 in the assembly lug tongue 21.

In Figure 5 a barrel portion 35 is shown integral with and extending from a receiver portion 36. A circumferential groove 3'! is formed about the barrel portion 35 adjacent the forward end 33 of the receiver portion 35 to provide a shoulder 39. The opening a i, in the assembly lug e2, corresponding to the opening 24 in the previously described form, is of suificient diameter to permit the assembly lug to be slipped over the barrel portion 35 and seated. in the groove 3! to abut the shoulder 39 and thus properly locate the associated parts as in the previously described form.

By the provision of the above described novel structure in a firearm, the parts constituting such structure may be readily and accurately assembled together in the proper and desired location in respect to each other and firmly secured together as so located. The particular form of assembly lug whereby the magazine and barrel are assembled and held in the desired position and whereby the magazine may be swung about the barrel to align it with a locating groove in the receiver provides for rapid and accurate assembly of these parts together. By the addition of the tongue Z? these assembled parts may readily and accurately be assembled to the buttstock.

While there has been shown and described herein two forms of firearm improvement in which the features and principles of this invention are embodied, it will be understood that the same may be embodied in other specific forms without departing from the spirit and essential attributes thereof, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being had to the claims rather than to the foregoing description to indicate the scope Of the invention.

Having thus fully disclosed the invention, what is claimed as new and for which it is desired to secure Letters Patent, is:
